text: On 31 May 2019, Mount Polley mine was put on care and maintenance status. Remediation work in the areas affected by the 2014 breach has been the focus of Mount Polleys staff from 2014 to 2019. While the mines closure affected mining operations, it did not impact the ongoing environmental monitoring and remediation programs.
  Care and maintenance at the Mount Polley mine included management of the water treatment facilities and the operation of site water management systems, including pumps and ditches. Mount Polley monitors the stability of the tailings storage facility on a regular basis. Mount Polley employed 15 staff at the site while it operated in care and maintenance status.
  The company reopened mine operations in July 2022.
